Hair Samples For DNA Analysis

Hair is one of the most common items used to get DNA. To get a good sample to use, the crime scene investigator needs the root. The root most often comes out at a crime scene during a struggle when hair is pulled out. Crime scene investigators who have to collect a sample of hair from a rape suspect often choose the pubic area to pull from. Not because they have to, but because it hurts, They'll take a pair of forceps and grab as much hair as possible and jerk it out with excruciating delight. This gives them a good and bloody sample from which to draw DNA.
